Ostropoloid fungus on Ammophila
Enrique Rubio, 11-05-2015 19:21

Hi to everybody


This Karstenia species was found on debris of Ammophila arenaria. This fungus seems to match with Karstenia idaei, a fungus that we found commonly on subalpine woody sustrates, but I have doubts with Karstenia macer a species that I don't know although it has a negative asci IKI reaction. 


Can you help me?


Thanks again

Re : Ostropoloid fungus on Ammophila
I can hardly believe that the asci are negative. Did you try with KOH-pretreatment?

K. idaei is really a good option, though the spores are a bit narrow. K. macer is usually with grey-olive exterior.

Thanks Zotto. Tomorrow I'll try the KOH pret. of the asci
